Equipment Schedule Example

Does someone have an example on all the uses of the Equipment Schedule. The wiki lacks a bit of information.
Would be nice to have an example where all funcionalities are shown.

Just as an example, I don't trully understand what a "down-time" is. I don't really understand the difference between using the lead time or the progress bar...
Any help is appreciatted, my first language is not english so I think I have some barrier in some terms.

Thanks!
